So, as we all know, Aether has been THE place to gather for anything regarding content in FFXIV - from ranging between Crafting and Gathering, it's been practically the only place where content that isn't MSQ is done. Alliance Raids, Raids in general, and most importantly, EX/Savage/Ultimate.
While yes, it was branded the raiding DC for a long time by NA, the community has decided that with the advent of DC travel that everyone go to Aether for any challenging content.
This has led to issues queueing for content on Home Worlds, as you lose a lot of functions if you decide to Data Center Travel. This link here shows you the limitations.
Even when I've queued for a raid series on my home world when I wanted to see how long it'd take for me to get through normally on some of the instances people hate, and it wound up being 2 HOURS for it. One of the more recent ones I went through was Weeping City of Mhach, which caused a lot of issues.
I had to shout in Limsa to even get people to join since it takes forever it seems to get in.
This then creates a major issue for new players who haven't heard of the Data Center Travel system(as the game DOES NOT point you to do such). While they can do other things while waiting, having to wait 2 hours to get into a singular raid to progress the story for the raid series is frustrating and at most will turn people off even trying them even if they're required for Alliance Raid roulette.
It goes to show that even in normal content, Aether literally just takes precedence in every respect due to the massive amount of the NA playerbase congregating in one area. Sure, it's great and all, but what's happening is that you're inconveniencing others on your own Home Worlds. Sure, you may not care about the Marketboard or anything else, but it's giving sprouts a hard time doing that content they want to try.
As for an actual solution? The Cloud.
Yes, The Cloud Test. It's showed it can handle heavy stress, and I think it's high time that SE made it to where if you want to queue for content, they put that Cloud to use for instance servers so people can actually get into things and not wait forever. While I'd imagine it'd take a lot to get the infrastructure up, we desperately need Cross DC Duty Finder in order to fix this issue and get people to go back to their Home Worlds so that the respective DCs(Crystal, Primal, DYNAMIS) aren't always pressured to go to Aether to do content.
